为了探究大丽花轮枝孢激活蛋白(Verticilliam dahliae Allergen Asp f2-like,VdAL)干粉制剂对黄瓜商品苗贮藏质量的影响,以黄瓜幼苗为试验材料,在育苗期进行了3次不同浓度叶面喷施处理,分析贮藏前与贮藏4 d后黄瓜幼苗质量相关指标以及定植后3~6 d恢复生长指标。结果表明:1.25 g·L~(-1)大丽花轮枝孢激活蛋白处理可以显著增强黄瓜幼苗的耐贮运性,与其他处理相比,该处理浓度贮藏过程中叶绿素含量稳定,定植后恢复生长快,表明育苗期叶面喷施适宜浓度的大丽花轮枝孢激活蛋白,有利于提高黄瓜商品苗的贮藏质量。
In order to investigate the effect of dry powder formulations of Verticilliam dahliae Allergen Asp f2-like (VdAL) on the storage quality of cucumber commercial seedlings, cucumber seedlings were used as test materials and three different concentrations of foliar spray The indexes related to the quality of cucumber seedlings before and after storage for 4 days and the indexes for recovery of growth after 3 ~ 6 days were analyzed. The results showed that the treatment with 1.25 g · L -1 Dahlia variabilis could significantly increase the storability of cucumber seedlings. Compared with other treatments, the content of chlorophyll was stable during storage and resumed after planting Fast, indicating that the appropriate concentration of foliar spray seedlings stage Dahlia fulvum activator protein, help to improve the storage quality of cucumber commodity seedlings.
